This is pure fantasy.
The secessionists recognized the Corwin Amendment as a last minute attempt to hold the country together. The proposed Amendment did nothing to overcome their fear and their hatred of the Republicans.
Actually what the Corwin Amendment did was offer the original 7 seceding states no relief from the crushing tariff burden the Morrill tariff would impose.
The Deep South states were already gone when Lincoln took office. They’d gotten what they wanted. They assumed that slavery and their way of life would be secure as an independent nation.
No they didn't. Many recognized that slavery would be quickly doomed. There was no way they could secure the border. What they wanted was commercial independence. That's what they got via seceding. If they were commercially independent, their profits would soar. Even with slavery ending, the profits from low tariff trade and handling the export portion of it themselves would have easily enabled them to pay wages and still be far richer. Several Northern Newspapers pointed out that the South would win via secession and the North would lose.
"The Southern Confederacy will not employ our ships or buy our goods. What is our shipping without it? Literally nothing. The transportation of cotton and its fabrics employs more than all other trade. It is very clear the South gains by this process and we lose. No, we must not let the South go." The Manchester, New Hampshire Union Democrat Feb 19 1861
They weren’t going to do a U-turn and come back. And yes, the Corwin Amendment wouldn’t do anything about the fear of Northern abolitionists and slave revolts.
They weren't going to come back because that would have meant subjecting themselves to the economically devastating Morrill Tariff. Preservation of slavery was obviously not the main concern since slavery was much safer within the union than outside of it. In addition to that, slave owners represented less than 6% of the White Southern population. Everybody would be affected by the Morrill tariff however - not just less than 6% of the population.
Excluding the plantation owner class and the urban residents of the few cities that the South had, the vast majority of the Southern population was made up of subsistence farmers. These farmers were largely self-sufficient. What they did not produce on their own would be locally produced items like horseshoes, plows, hand tools, firearms, tobacco, coffee. Save for coffee, those items were produced locally or manufactured domestically. High tariffs would have little effect on their lives. These farmers fought for the Confederacy due to their loyalty to their home states, not for economic benefits. The plantation owners were leaders in their communities, and it is worthy to note that the Unionist areas in the South, such as East Tennessee, were areas where there were no plantations.
I thought I told you not to post to me. I guess I didn’t. So I’ll tell you now. You are so full of nonsense that I can’t be bothered with you. Diogenes is full of nonsense too, but I got used to having him around.
